Ear loop welder 28KHz 35KHz 800W ultrasonic spot welding machine
When the ultrasonic wave acts on the contact of thermoplastic materials, it will produce tens of thousands of high-frequency vibrations per second. This kind of high-frequency vibration with a certain amplitude will produce local high temperature. Because of the poor thermal conductivity of plastic, the temperature can not be distributed in time for a time, which will gather in the welding area, resulting in the rapid melting of the contact surface of the two plastics. After a certain amount of pressure is applied, it is integrated. When the ultrasonic wave stops acting, the pressure is allowed to last for several seconds to solidify and form a solid molecular chain to achieve the purpose of welding. The strength is close to the strength of raw materials.
